Definitions

  • the invention relates to a bending beam for door impact profiles, bumpers, body reinforcements or the like, consisting of a hollow profile with a flat force application surface and with at least two opposite plane-parallel deformation surfaces, which are arranged perpendicular to the force application surface.
  • a bending beam of the type mentioned is known from DE-OS 36 06 024 (aluminum rolling mill Singen).
  • the profile walls enclose a profile chamber with a pair of transverse walls connecting them, the profile walls projecting beyond the outer surfaces of the transverse walls to form bead sections.
  • the known bending beam is designed according to the maximum force to be absorbed, which determines the cross section of the profile chamber over the entire length.
  • the force-displacement diagram is constant over the entire bending beam (see FIG. 11 of DE-OS 36 06 024).
  • the force-displacement diagrams are usually carried out according to the regulations of Federal Motor Vehicle Safety Standard No. 214 (FMVSS).
  • FMVSS Federal Motor Vehicle Safety Standard No. 214
  • the force application point and the pressure direction of a hemispherical pressure body and the stamp path of the test body are specified.
  • a bending support for automobile doors which consists of a corrugated rolled profile seen in cross section.
  • the corrugated profile can be welded with plate-shaped additional elements in the direction of force application.
  • the resulting stiffening body is widened in the direction of the force application, whereby the space available for further installations, such as. B. windows or locking linkage, downsized.
  • the installation height of this known flexible beam is therefore too large for many applications.
  • the object of the present invention is to develop a weight-optimized bending beam for door impact profiles, bumpers, body stiffeners or the like, which, for a given installation height h in the direction of force application, has a maximum of bending stiffness with the lowest possible weight, can be produced as a large-scale part, and can be changed slightly to different load cases is customizable.
  • the stiffeners can be symmetrical on both sides and not symmetrical to the direction of force application, in accordance with the requirements of the bending stress.
  • they are preferably connected to the bending beam in a positive and non-positive manner by suitable joining. It is particularly advantageous if the additional profile is equipped with a fiber reinforcement to increase the modulus of elasticity of the bending beam.
  • Particle-reinforced extruded profiles which are dispersion-hardened can also be used as stiffeners.
  • bending beam 1 is shown with deformation surfaces 2, 3, each additionally having a dovetail 6, 7.
  • Additional profiles 4, 5 are positively connected by means of dovetail grooves 8, 9 via the dovetails.
  • the length L denotes the total width of additional profiles 4, 5 and bending beam 1 transverse to the direction of force application.
  • the height h denotes the thickness of the bending beam or the additional profiles in the direction of force application.
  • Fig. 2 the bending beam 1 is shown with additional profiles 4, 5, which do not go over the entire length of the bending beam 1.
  • the additional profiles 4, 5 are positively attached to the dovetails 6, 7, which in turn are arranged on the deformation surfaces 2, 3 of the bending beam 1.
  • the essential finding of the present invention is that the stiffeners (ie the additional profiles 4, 5) can be adapted to the respective load by changing the side length.
  • the flexible beams with dovetail grooves or dovetails can be manufactured as large series parts and combined with additional profiles of different lengths.
  • the positive connection ensures a complete transfer of the bending forces.
